Thank you for the input, Edgar. The consideration of disabling flow control is to avoid a pause packet going to a server with clients depending on it for ltsp. Such a pause closes off all the clients for whatever time the packet requests. In the configurations originally presented no two ports which are in communication are different. All 100 Mbps nics are connected to 100 Mbps ports on the switch and the one giga nic on the server is connected to the one giga port on the switch. The issue here is that the buffer on the switch fills from data from its giga port while data is more slowly released through its 100 Mbps ports. What is hoped is that with flow control disabled the server will slow down (or pause for less time) to allow the switch's buffer time to empty enough to accommodate new data arriving. Anyone with more of an understanding of these processes is invited to correct this.
